摘要：

Tokyo Electric Power's Kazunogawa Power Station will, when completed, be Japan's largest pumped-storage hydroelectric power station, with an output of 1.6 GW. The first phase is currently under construction, with two 400-MW machines and one cable circuit. Using leading-edge technology Furukawa Electric has provided 500-kV XLPE cable and associated extrusion-molded joints (EMJs) and horizontal gas-immersed sealing ends (EBGs) for the No. 1 and No. 2 machines. Construction was completed in November 1998 and voltage withstand tests have also been performed. The cable for this line is 2300 m in length, longer than has ever been used in a power station interconnect. Because of transportation constraints, insulation-type EMJs are installed at intermediate points. The line is being built under the same basic design concept and installation conditions as the Shin-Keiyo-Toyosu Line now under construction, and reflects the expertise and knowhow acquired there. The equipment covered here is scheduled to go into service in December, 1999.
